# Gridism
A simple responsive CSS grid. [View the demo →](http://cobyism.com/gridism/)
## Why?
### My process
When I design web layouts, my thought process usually goes something like this:
> Alright, in this section, I want a bit that’s one third of the section’s width,
> and then next to that I want another bit that’s two thirds of the sections’s width.
> Now, in the next section…
I don’t think in 12 or 16 column grids. Instead, my mental model basically just consists of the page being divided up into multiple full-width vertical sections, and each vertical section being divided up into simple fractions of the section width.
### Existing grid frameworks
Most frameworks I’ve used don’t match that thought process *at all*. I usually have to:
1. Remember how many columns are in the grid for the particular framework I’m using.
1. Decide how I want to divide up this particular section’s content.
1. Mentally do the conversion from what I want to see (one quarter + three quarters, for example) into the number of columns I need for the grid I’m using.
1. Remember the class naming structure for the framework I’m using. Is it `.span3`, `.grid_3`, `.col-3`, or something else altogether?
1. Deal with other hassles like clearing floats, messing with column padding to have the gutters look right, indicating which elements are the first in a row, and so forth.
Only the second step should be necessary.
### Gridism’s Goals
I couldn’t find a framework that matched this mental model of how I work, so I started hacking on Gridism with the following goals:
- Class names should be memorable and self-evident.
- Gutters and basic content padding should be taken care of.
- Clearing floats should be done automatically.
- Wrapped grid sections should be independant of vertical page sections.
- Frequently required utility classes should be provided.
- Common patterns for Responsive Design™ should be built-in.
I hope you find that this project is living up to those goals. If not, please [create an issue](https://github.com/cobyism/gridism/issues/new) and let me know.
## Installation
### 1. Get the files
The easiest way to use Gridism in your project is via the [Bower](http://twitter.github.com/bower) package manager.
```sh
bower install gridism
```
Elsewise, [download the zip folder](https://github.com/cobyism/gridism/archive/gh-pages.zip), extract it, and copy `gridism.css` into your project’s folder. Boom. Done.
### 2. Link the stylesheet
Add the following stylesheet to your HTML’s `<head>` section:
```html
<link rel="stylesheet" href="bower_components/gridism/gridism.css">
```
**Note:** If you didn’t install using Bower, you need to adjust the path of CSS file to match your file structure.
### 3. Viewport scale
Add the following meta tag to your HTML’s `<head>` section:
```html
<meta name="viewport" content="width=device-width,initial-scale=1">
```
Without this meta tag, mobiles and tablets might load your page as a scaled-down version of the desktop size, instead of resizing the content to match the device’s actual viewport width.
## Contributing
I’d :heart: to receive contributions to this project. It doesn’t matter if it’s just a typo, or if you’re proposing an overhaul of the entire project—I’ll gladly take a look at your changes. Fork at will! :grinning:.
## License
Go nuts. See [LICENSE](https://github.com/cobyism/gridism/blob/gh-pages/LICENSE) (MIT).

# &lt;qr-code&gt;
Web Component for generating QR Codes, using (a [fork](https://github.com/educastellano/qr.js) of) [qr.js](https://github.com/lifthrasiir/qr.js) lib.
> Maintained by [Eduard Castellano](https://github.com/educastellano).
## Demo
> [Check it live](http://educastellano.github.io/qr-code/demo).
## Usage
* **NPM and Browserify** ([polyfill](https://github.com/WebComponents/webcomponentsjs) and the component):
Install:
```sh
npm install webcomponents.js
npm install webcomponent-qr-code
```
Import:
```js
require('webcomponents.js');
require('webcomponent-qr-code');
```
* **Bower** ([polyfill](https://github.com/WebComponents/webcomponentsjs), [qr.js](https://github.com/educastellano/qr.js) and the component):
Install:
```sh
bower install webcomponentsjs
bower install webcomponent-qr-code
```
Import:
```html
<script src="bower_components/webcomponentsjs/webcomponents.min.js"></script>
<script src="bower_components/qrjs/qr.js"></script>
<script src="bower_components/webcomponent-qr-code/src/qr-code.js"></script>
```
> You can also import the component with [HTML Imports](http://w3c.github.io/webcomponents/spec/imports/), but you still need to import the polyfill and the qr.js lib separately:
>
> ```html
> <link rel="import" href="bower_components/webcomponent-qr-code/src/qr-code.html">
> ```
* **Start using it!**
```html
<qr-code data="hello world!"></qr-code>
```

# QRCode.js
QRCode.js is javascript library for making QRCode. QRCode.js supports Cross-browser with HTML5 Canvas and table tag in DOM.
QRCode.js has no dependencies.
## Basic Usages
```
<div id="qrcode"></div>
<script type="text/javascript">
new QRCode(document.getElementById("qrcode"), "http://jindo.dev.naver.com/collie");
</script>
```
or with some options
```
var qrcode = new QRCode("test", {
text: "http://jindo.dev.naver.com/collie",
width: 128,
height: 128,
colorDark : "#000000",
colorLight : "#ffffff",
correctLevel : QRCode.CorrectLevel.H
});
```
and you can use some methods
```
qrcode.clear(); // clear the code.
qrcode.makeCode("http://naver.com"); // make another code.
```
## Browser Compatibility
IE6~10, Chrome, Firefox, Safari, Opera, Mobile Safari, Android, Windows Mobile, ETC.

# qr.js: QR code generator in pure Javascript (2011)
This is a fairly standalone script for producing QR code on the fly.
Originally developed for my own interest, the code is fully commented and well-structured.
The code is in the public domain (or to be exact, [Creative Commons Zero](https://creativecommons.org/publicdomain/zero/1.0/)),
and you can use it for absolutely any purpose.
See also a [node.js module based on qr.js](https://github.com/shesek/qruri), packaged by Nadav Ivgi.

* codes (ECC). There could be multiple ECCs, in the case the code is so large
* that it is helpful to split the raw data into several chunks.
*
* The number of modules is determined by the code's "version", ranging from 1
* (21x21) to 40 (177x177). How many ECC bits are used is determined by the
* ECC level (L/M/Q/H). The number and size (and thus the order of generator

webcomponents.js
================
[![Join the chat at https://gitter.im/webcomponents/webcomponentsjs](https://badges.gitter.im/Join%20Chat.svg)](https://gitter.im/webcomponents/webcomponentsjs?utm_source=badge&utm_medium=badge&utm_campaign=pr-badge&utm_content=badge)
A suite of polyfills supporting the [Web Components](http://webcomponents.org) specs:
**Custom Elements**: allows authors to define their own custom tags ([spec](https://w3c.github.io/webcomponents/spec/custom/)).
**HTML Imports**: a way to include and reuse HTML documents via other HTML documents ([spec](https://w3c.github.io/webcomponents/spec/imports/)).
**Shadow DOM**: provides encapsulation by hiding DOM subtrees under shadow roots ([spec](https://w3c.github.io/webcomponents/spec/shadow/)).
This also folds in polyfills for `MutationObserver` and `WeakMap`.
## Releases
Pre-built (concatenated & minified) versions of the polyfills are maintained in the [tagged versions](https://github.com/webcomponents/webcomponentsjs/releases) of this repo. There are two variants:
`webcomponents.js` includes all of the polyfills.
`webcomponents-lite.js` includes all polyfills except for shadow DOM.
## Browser Support
Our polyfills are intended to work in the latest versions of evergreen browsers. See below
for our complete browser support matrix:
| Polyfill | IE10 | IE11+ | Chrome* | Firefox* | Safari 7+* | Chrome Android* | Mobile Safari* |
| ---------- |:----:|:-----:|:-------:|:--------:|:----------:|:---------------:|:--------------:|
| Custom Elements | ~ | ✓ | ✓ | ✓ | ✓ | ✓| ✓ |
| HTML Imports | ~ | ✓ | ✓ | ✓ | ✓| ✓| ✓ |
| Shadow DOM | ✓ | ✓ | ✓ | ✓ | ✓ | ✓ | ✓ |
| Templates | ✓ | ✓ | ✓ | ✓| ✓ | ✓ | ✓ |
*Indicates the current version of the browser
~Indicates support may be flaky. If using Custom Elements or HTML Imports with Shadow DOM,
you will get the non-flaky Mutation Observer polyfill that Shadow DOM includes.
The polyfills may work in older browsers, however require additional polyfills (such as classList)
to be used. We cannot guarantee support for browsers outside of our compatibility matrix.
### Manually Building
If you wish to build the polyfills yourself, you'll need `node` and `gulp` on your system:
* install [node.js](http://nodejs.org/) using the instructions on their website
* use `npm` to install [gulp.js](http://gulpjs.com/): `npm install -g gulp`
Now you are ready to build the polyfills with:
# install dependencies
npm install
# build
gulp build
The builds will be placed into the `dist/` directory.

## Helper utilities
### `WebComponentsReady`
Under native HTML Imports, `<script>` tags in the main document block the loading of such imports. This is to ensure the imports have loaded and any registered elements in them have been upgraded.
The webcomponents.js and webcomponents-lite.js polyfills parse element definitions and handle their upgrade asynchronously. If prematurely fetching the element from the DOM before it has an opportunity to upgrade, you'll be working with an `HTMLUnknownElement`.
For these situations (or when you need an approximate replacement for the Polymer 0.5 `polymer-ready` behavior), you can use the `WebComponentsReady` event as a signal before interacting with the element. The criteria for this event to fire is all Custom Elements with definitions registered by the time HTML Imports available at load time have loaded have upgraded.
```js
window.addEventListener('WebComponentsReady', function(e) {
// imports are loaded and elements have been registered
console.log('Components are ready');
});
```
## Known Issues
* [Limited CSS encapsulation](#encapsulation)
* [Element wrapping / unwrapping limitations](#wrapping)
* [Custom element's constructor property is unreliable](#constructor)
* [Contenteditable elements do not trigger MutationObserver](#contentedit)
* [ShadowCSS: :host-context(...):host(...) doesn't work](#hostcontext)
* [ShadowCSS: :host(.zot:not(.bar:nth-child(2))) doesn't work](#nestedparens)
* [HTML imports: document.currentScript doesn't work as expected](#currentscript)
* [execCommand isn't supported under Shadow DOM](#execcommand)
### Limited CSS encapsulation <a id="encapsulation"></a>
Under native Shadow DOM, CSS selectors cannot cross the shadow boundary. This means document level styles don't apply to shadow roots, and styles defined within a shadow root don't apply outside of that shadow root. [Several selectors](http://www.html5rocks.com/en/tutorials/webcomponents/shadowdom-201/) are provided to be able to deal with the shadow boundary.
The Shadow DOM polyfill can't prevent document styles from leaking into shadow roots. It can, however, encapsulate styles within shadow roots to some extent. This behavior isn't automatically emulated by the Shadow DOM polyfill, but it can be achieved by manually using the included ShadowCSS shim:
```
WebComponents.ShadowCSS.shimStyling( shadowRoot, scope );
```
... where `shadowRoot` is the shadow root of a DOM element, and `scope` is the name of the scope used to prefix the selectors. This removes all `<style>` elements from the shadow root, rewrites it rules using the given scope and reinserts the style as a document level stylesheet. Note that the `:host` and `:host-context` pseudo classes are also rewritten.
For a full explanation on the implementation and both the possibilities and the limitations of ShadowCSS please view the documentation in the [ShadowCSS source](src/ShadowCSS/ShadowCSS.js).
### Element wrapping / unwrapping limitations <a id="wrapping"></a>
The Shadow DOM polyfill is implemented by [wrapping](http://webcomponents.org/polyfills/shadow-dom/#wrappers) DOM elements whenever possible. It does this by wrapping methods like `document.querySelector` to return wrapped DOM elements. This has a few caveats:
* Not _everything_ can be wrapped. For example, elements like `document`, `window`, `document.body`, `document.fullscreenElement` and others are non-configurable and thus cannot be overridden.
* Wrappers don't support [live NodeLists](https://developer.mozilla.org/en-US/docs/Web/API/NodeList#A_sometimes-live_collection) like `HTMLElement.childNodes` and `HTMLFormElement.elements`. All NodeLists are snapshotted upon read. See [#217](https://github.com/webcomponents/webcomponentsjs/issues/217) for an explanation.
In order to work around these limitations the polyfill provides the `ShadowDOMPolyfill.wrap` and `ShadowDOMPolyfill.unwrap` methods to respectively wrap and unwrap DOM elements manually.
### Custom element's constructor property is unreliable <a id="constructor"></a>
See [#215](https://github.com/webcomponents/webcomponentsjs/issues/215) for background.
In Safari and IE, instances of Custom Elements have a `constructor` property of `HTMLUnknownElementConstructor` and `HTMLUnknownElement`, respectively. It's unsafe to rely on this property for checking element types.
It's worth noting that `customElement.__proto__.__proto__.constructor` is `HTMLElementPrototype` and that the prototype chain isn't modified by the polyfills(onto `ElementPrototype`, etc.)
### Contenteditable elements do not trigger MutationObserver <a id="contentedit"></a>
Using the MutationObserver polyfill, it isn't possible to monitor mutations of an element marked `contenteditable`.
See [the mailing list](https://groups.google.com/forum/#!msg/polymer-dev/LHdtRVXXVsA/v1sGoiTYWUkJ)
### ShadowCSS: :host-context(...):host(...) doesn't work <a id="hostcontext"></a>
See [#16](https://github.com/webcomponents/webcomponentsjs/issues/16) for background.
Under the shadow DOM polyfill, rules like:
```
:host-context(.foo):host(.bar) {...}
```
don't work, despite working under native Shadow DOM. The solution is to use `polyfill-next-selector` like:
```
polyfill-next-selector { content: '.foo :host.bar, :host.foo.bar'; }
```
### ShadowCSS: :host(.zot:not(.bar:nth-child(2))) doesn't work <a id="nestedparens"></a>
ShadowCSS `:host()` rules can only have (at most) 1-level of nested parentheses in its argument selector under ShadowCSS. For example, `:host(.zot)` and `:host(.zot:not(.bar))` both work, but `:host(.zot:not(.bar:nth-child(2)))` does not.
### HTML imports: document.currentScript doesn't work as expected <a id="currentscript"></a>
In native HTML Imports, document.currentScript.ownerDocument references the import document itself. In the polyfill use document._currentScript.ownerDocument (note the underscore).
### execCommand and contenteditable isn't supported under Shadow DOM <a id="execcommand"></a>
See [#212](https://github.com/webcomponents/webcomponentsjs/issues/212)
`execCommand`, and `contenteditable` aren't supported under the ShadowDOM polyfill, with commands that insert or remove nodes being especially prone to failure.
